Abstract
Description
- The invention relates to a device to create a hermetic seal for large openings in equipment subject to low pressure.
- In order to seal openings in equipment, round flanges are normally welded into the opening and a suitable cover with seals is applied. To prevent the seal surfaces from warping, they must have a substantial material thickness and also be machined. For pressure vessels in the medium and high pressure range, the material must be very thick in any case in order to lend the equipment the required strength. At low pressures and for equipment used in air engineering systems, the wall thickness is only a few millimetres and thus cannot guarantee that the sealing surfaces are rigid enough and free of warping, particularly for large, mainly rectangular opening cross-sections. Large cross-sections are needed for assembly and access ports, for example, or for built-in components such as agitators and heat exchangers.
- The aim of the invention is thus to create a device that guarantees a simple, low-cost and hermetic seal at low pressures.
- The invention is thus characterised by at least one sealing cover being provided, which is pressed onto the side wall of the equipment by means of bolts, where the bolts are mounted in a strip attached to the side wall at the edge of the opening in the equipment, where the opening can advantageously have a rectangular shape. When the device according to the invention is used, the low wall thickness required by the engineering design can be retained, while still achieving a hermetic seal. In particular, there is no need for laborious machining of the sealing surface on the vessel side. This results in an economical advantage in the equipment design.
- It has proved particularly favourable if the strip is pressed onto the side wall by means of U-shaped profiles. This ensures that it is pressed on evenly.
- A favourable further embodiment of the invention is characterised by the sealing cover having a groove for a soft seal. This provides a very good hermetic seal.
- If there are several openings with sealing covers, it is particularly advantageous if sealing covers that are close together are clamped to a shared profile.
- A favourable embodiment of the invention is characterised by the bolts being pushed or screwed into the strip, where the bolts can either be glued or welded to the strip.
- The invention proves particularly advantageous if the sealing cover is part of a heat exchanger stack, where the heat exchanger stack can be aligned precisely with the aid of running rails and adjustable suspension rollers in such a way that the sealing cover is plane-parallel to the side wall.
- The invention will now be described in examples and referring to the drawings, where
-
FIG. 1 shows an embodiment of the invention, -
FIG. 2 shows a sectional view along the line marked II-II inFIG. 1 , -
FIG. 3 shows a sectional view along the line marked III-III inFIG. 1 , -
FIG. 4 shows a sectional view of a strip according to the invention, and -
FIG. 5 shows a further embodiment of the invention. -
FIG. 1 shows asealing cover 1 that is clamped to theside wall 5 by means of U-shapedprofiles 2 usingbolts 3 that are welded to astrip 4. Thestrips 4 are welded to the side wall at the edge of theopenings 7 and thus reinforce the sealing area of the side wall. Together with the U-shapedprofiles 2, this creates an extremely rigid structure for the sealing area. -
FIG. 2 shows a sectional view along the line marked II-II inFIG. 1 , where twoopenings 7 are visible here. Thestrip 4 is welded to theside wall 5 of the equipment. For sealing purposes there is a U-shapedprofile 2 that is connected to thestrip 4 bybolts 3 and presses both sealingcovers 1 onto theside wall 5. Asoft seal 6 placed in the circumferential cover groove in the cover levels out any remaining imprecision in the surface and thus provides a hermetic seal at the opening(s) 7. For openings adjacent to one another, clamping can be achieved in a space-saving arrangement by using a shared U-shapedprofile 2 which then has side sections of the same height. In contrast, the side sections for clamping directly to theside wall 5 are not the same height (as also shown inFIG. 3 (sectional view along the line marked III-III inFIG. 1 ). - The
strips 4 have the twin function of stiffening and clamping. Advantageously they have a high, or at least a square cross-section. Thebolts 3 are placed or screwed into the holes and welded into place from the rear (seeFIG. 4 ). The strips are then welded to the side wall by means of simple fillet welds following any aligning work that may be necessary. - If there are not only
openings 7 to be closed off, but also heat exchanger stacks, for example, that are to be pushed into the equipment from the side, additional measures are required. As shown inFIG. 5 , it is advantageous if the heat exchangers also have asealing plate 1 at their outer end, as described above. The inlet and outlet of thepipe coils 8 lead intocollection pipes 9 on the outside. The passages through thesealing plate 1 are seal-welded. At their inner end thepipe coils 8 are secured to aholding frame 10. Thisholding frame 10 can be connected directly to thesealing plate 1 by means of stiffener plates (not shown), which results in a compact unit. If the insertion depths are large, however, the reinforcedside wall 5 according to the invention is not able to withstand the bending weights. As a remedial measure, the side walls facing one another are connected by means of runningrails 12, which alone provide some reinforcement. Furthermore, theholding frame 10 of the heat exchanger is suspended from the runningrails 12 onadjustable rollers 11. When the heat exchanger stack has been pushed into the equipment, thesealing plate 1 can be aligned plane-parallel to theside wall 5 and thus is not exposed to any additional moments of flexion that cause leakage. The sealing plate is secured in place and sealed by means of U-shapedprofiles 2 and strips withbolts 4 according to the invention, as described above.
